There were seven puppies in the team. The others had been born earlier in the year and were nine and ten months old, while White Fang was only eight months old. Each dog was fastened to the sled by a single rope. No two ropes were of the same length, while the difference in length between any two ropes was at least that of a dog’s body. Every rope was brought to a ring at the front end of the sled. The sled itself was without runners, being a birch-bark toboggan, with upturned forward end to keep it from ploughing under the snow. This construction enabled the weight of the sled and load to be distributed over the largest snow-surface; for the snow was crystal-powder and very soft. Observing the same principle of widest distribution of weight, the dogs at the ends of their ropes radiated fan-fashion from the nose of the sled, so that no dog trod in another’s footsteps. There was, furthermore, another virtue in the fan-formation. The ropes of varying length prevented the dogs attacking from the rear those that ran in front of them. For a dog to attack another, it would have to turn upon one at a shorter rope. In which case it would find itself face to face with the dog attacked, and also it would find itself facing the whip of the driver. But the most peculiar virtue of all lay in the fact that the dog that strove to attack one in front of him must pull the sled faster, and that the faster the sled travelled, the faster could the dog attacked run away. Thus, the dog behind could never catch up with the one in front. The faster he ran, the faster ran the one he was after, and the faster ran all the dogs. Incidentally, the sled went faster, and thus, by cunning indirection, did man increase his mastery over the beasts. Mit-sah resembled his father, much of whose grey wisdom he possessed. In the past he had observed Lip-lip’s persecution of White Fang; but at that time Lip-lip was another man’s dog, and Mit-sah had never dared more than to shy an occasional stone at him. But now Lip-lip was his dog, and he proceeded to wreak his vengeance on him by putting him at the end of the longest rope. This made Lip-lip the leader, and was apparently an honour! but in reality it took away from him all honour, and instead of being bully and master of the pack, he now found himself hated and persecuted by the pack. Because he ran at the end of the longest rope, the dogs had always the view of him running away before them. All that they saw of him was his bushy tail and fleeing hind legs—a view far less ferocious and intimidating than his bristling mane and gleaming fangs. Also, dogs being so constituted in their mental ways, the sight of him running away gave desire to run after him and a feeling that he ran away from them.
